Stephan, Thank you for the suggestion. This is odd. I don’t recall having this
problem before my upgrade to Mavericks. And very odd that is crops up in one
file but not another.
It looks like python fails to process something...
Here is the message log from a change to the figure in displays.lyx

Stephan,
My apologies. Here are two lyx files.
The one titled displays.lyx displays my diagram. The other one does not.
Doug,
that's better. But I have to say: both are working on my system -
a Mac with LyX-2.1.2 on OS X 10.8.6. I've noticed I have to click
somewhere sometimes to trigger the display of the preview snippet.
The two examples are different only regarding the \use_non_tex_fonts
and the \font_roman setting in the preferences.
What you can do to check for errors converting is to open the message
pane and enable the graphics conversion message. There you should see
the problem if one exists.

Dear Stephan,
Sure. On my screen I see
X\ar[r] Y
Instead of
X -> Y
Normally, when I am editing my diagram I see my xypic code and when I place the
cursor outside the editing area, the diagram converts from code to a picture.
Now, I see my code, but I do not see the picture when I place the cursor
outside the editing area.
Does this help?
Sorry, no it doesn't help. A minimal example is a complete LyX file.
See here: http://wiki.lyx.org/FAQ/MinimalExample

Thanks!

Hello! My xypic diagrams are not previewing in LyX. I can see the matrix with
the code, but no nice WYSIWYG picture with nodes and arrows. The file compiles
fine and the diagrams look good in the pdf. I have gone into preferences,
look&feel, display, display graphics is checked. TexLive is telling me that the
preview Latex package is installed. I reinstalled preview and xypic packages
anyway and that did not help. Other equations (e.g. \beta ) display fine. I
would appreciate any advice or short term workarounds. Thanks! Doug

Hello,
are you able to provide a minimal example to demonstrate your problem, please?
